-da suf. “verbal suffix”
The opposite of the agental suffix -ân, this is used to turn nouns into verbs.
Examples
ugru (“shadow”) à ugrudâ (“to overshadow”).
azgar (“war”) à azgarâ (“to (wage) war”). [1]
[1]. With a few exceptions, derived verbs cannot have more than three consonants, so in the case of azgar, the [d] in the suffix disappears, leaving just -â.
